Adversarial graph augmentation
WebIn general, GCL methods use graph data augmentation (GDA) processes to perturb the original observed graphs and decrease the amount of information they encode. Then, the methods apply InfoMax over perturbed graph pairs (using different GDAs) to train an encoder fto capture the remaining information.
